Safety in the workplace is DECCA’s Priority. DECCA has gained business accreditation in order to provide added confidence to clients and staff that we are discharging our responsibilities consistent with accepted and mandated standards.

We have gained accreditation of our IMS (Integrated Management System) under ISO 9001:2000, ISO 14001:2004 and AS/NZS 4801:2001. This accreditation is reviewed regularly to ensure we continue to surpass requirements.

We are proud members of the MBA (Master Builders Association) and the PCA (Property Council of Australia), and have a number of staff across our teams that are accredited professionals.
